purity-check

What problem does it solve?

This Skill verifies that the formal proof environment adheres strictly to Lean 4 core with no external axioms or imports, maintaining foundational purity.

Core Features & Use Cases

• Axiom verification: Checks for forbidden external axioms, Mathlib imports, classical logic, and native decision procedures.
• Falsifiability validation: Ensures the environment only uses a minimal set of axioms, enhancing proof reliability.
• Use Case: Before formal proof development, use this Skill to confirm zero external dependencies and purity compliance, especially in sensitive or foundational projects.

Quick Start

Run the purity check to validate that your Lean environment includes only the allowed axioms and imports as specified in the proof code.
